3M 7000044904 Cubitron Ii Roloc Fibre Disc 982C 80 Grit 3 in

Product Description

The 3M 7000044904 is a 3-inch Cubitron II Roloc Fibre Disc in the 982C series, engineered for medium to high pressure grinding on carbon steel. It uses 3M Precision Shaped Grain (PSG) technology, which maintains sharp cutting points to deliver fast material removal with less applied pressure. The 80-grit abrasive removes weld material, scale, and surface defects efficiently while running cooler than conventional abrasive grains. This reduces heat-related metal discoloration, oxidation, and the risk of stress cracking in the workpiece. A stiff fiber backing combined with a strong resin bond gives the disc durability and tear-resistance suited for demanding weld grinding and heavy fabrication work.

This disc is designed for use in fabrication shops, structural steel work, and weld cleanup applications where a compact 3-inch disc provides access to tight areas or smaller workpieces. The Roloc quick-change attachment system allows fast disc swaps between grits or disc types without tools, reducing downtime during production grinding. It is appropriate for use by metal fabricators, welders, and maintenance technicians working on carbon steel surfaces. The smaller disc diameter makes it well suited to angle grinders and die grinders equipped with a Roloc-compatible backup pad.

Key Features

• 3M Precision Shaped Grain (PSG) maintains super-sharp cutting points for fast stock removal with less pressure
• Cooler cutting action minimizes metal discoloration, oxidation, and heat-related stress cracking
• Extended disc life reduces part changes and increases parts completed per disc
• Roloc quick-change attachment system enables tool-free disc changes between grades or applications
• Stiff fiber backing and strong resin bond deliver durability and tear-resistance for high-pressure weld grinding
• 80-grit configuration balances cut rate and surface finish for medium to heavy stock removal

Compatibility

Designed for use with Roloc-compatible backup pads on angle grinders and die grinders. Intended for medium to high pressure grinding applications on carbon steel surfaces.

Installation Notes

Installation and disc changes should be performed by qualified operators following the grinder and backup pad manufacturer guidelines. Ensure the grinder is powered off and unplugged, or the air supply is disconnected, before mounting or removing the disc. Verify that the grinder RPM rating meets or exceeds the maximum rated speed of the disc before operation. Wear appropriate personal protective equipment including eye protection, a face shield, and gloves during grinding operations.
